What Bariatric Operation Is The Best Weight Loss Surgery:

Gastric Sleeve vs Gastric Bypass has been the debate for a long time and we are here to finally settle it. Stick to the end to find out what’s the best option for you! Our only recommendation is to do your research and go to a reliable clinic to get the best treatment. With that said, let’s dive right in!

Gastric Bypass Surgery:

Gastric Bypass surgery is usually done laparoscopically with small incisions in the abdomen. The surgeon creates a small stomach pouch by dividing the stomach into two parts and then re-connecting the intestine to it. This limits the amount of food that you can eat, as well as how much your body can absorb. Since the body can no longer absorb more food, a process called “malabsorption” takes place where you start losing weight due to lack of calorie uptake.

Why is it done?

Gastric bypass is mainly done to help you lose weight but there are other health benefits to it as well like reducing the chance of obesity related diseases. These include:

  • Gastroesophageal Reflux Disease
  • Obstructive Sleep Apnea
  • High Cholesterol
  • High Blood Pressure
  • Stroke
  • Type 2 Diabetes
  • Infertility

Gastric Sleeve Surgery:

In gastric sleeve surgery, the surgeon removes about 80% of the stomach so that it takes on a banana shape. The surgeon cuts three-fourths of your stomach and staples the rest of the gut back together. This greatly reduces the size of the stomach and you are unable to eat a lot. Malabsorption takes place again and you eventually lose weight.

Why is it done?

Gastric sleeve is for people who want to fight obesity but are unable to do it on their own. It helps with most of the same diseases we mentioned for gastric sleeve and helps you move toward a healthier lifestyle. It is important to know that these surgeries are irreversible and cannot be undone so make sure you want it before going in. Having a word with your doctor can help you through the process. If you go to a trustworthy clinic like Dr Feiz, their experienced team of doctors can help you make a more informed decision.


Both surgeries have different aftercare. With gastric bypass surgery, you are advised to eat a healthy diet and take your vitamins regularly. You also need to go for regular checkups with the surgeon so that they can monitor your progress. If you don’t follow their instructions properly, you might experience problems like vomiting, nausea or malnutrition.

Gastric sleeve surgery is slightly less complicated than gastric bypass surgery. However, it’s still important to eat healthy foods and take your vitamins so that you don’t experience any complications post-surgery. You also need to go for regular checkups but the frequency might be lower than with gastric bypass surgery.

As for the diet, you are required to drink water and clear liquids for the first week and then you can slowly nurse back to health and a regular diet, starting with pureed foods and vegetables. Don’t drink alcohol until you fully recover and your doctor clears you for it.


Although gastric sleeve is a less complicated procedure as compared to gastric bypass, bypass has been performed for the longest time. Gastric sleeve is safer so that is our recommendation however let your doctor examine you thoroughly and decide the best weight loss surgery for you. If you made it to the end of this blog, we believe you are more than ready to make the right decision for yourself!
